Studies on dental units (DUs) are conducted either for the prevention or the reduction of the density of bacterial contamination in dental unit waterlines (DUWLs). However, the existence of fungi in the these systems requires more attention. During dental treatment, direct contact with water contaminated with fungi such as Candida, Aspergillus, or inhalation of aerosols from high-speed drill ma...

BACKGROUND The objective of the study was to explore the reach of an ongoing hepatitis B vaccination programme in terms of awareness of the programme among drug users (DUs), vaccination uptake and compliance, as well as to investigate reasons for non-participation. METHODS Ethnographic mapping and targeted sampling were used to recruit 309 DUs in three regions in the Netherlands. Results were...

Abstract There is a need to comprehend real-world problems that are marked by ambiguity and inflexibility. By taking into account the indeterminacies inconsistencies, DUS transformation has been taken Neutrosophic Weibull distribution DUS-Neutrosophic proposed. The probability density function unimodal decreasing in nature. Several statistical properties have studied. parameters of proposed est...

The transition period of post-socialist cities brought significant demographic and spatial changes within their daily urban systems (DUS). Functional transformations the core, as well functionally dependent settlements in mentioned systems, had a impact on mobility population. For purposes this paper, example Belgrade was taken core most DUS territory Serbia, beyond its borders. As research tim...

BACKGROUND Duplex ultrasound (DUS) has shown a >90% accuracy compared to angiography, concerning the degree of internal carotid artery (ICA) stenosis. However, uncertainty may occur in a severe stenosis, in which peak systolic velocity (PSV) may decrease owing to high flow resistance or high backward pressure. We investigated intracranial collateral flows using transcranial Doppler (TCD) to fur...

The European Union Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) Regulation (EC 1907/2006) places significant new obligations on the manufacturers or importers (M/Is) of chemicals in Europe. It also places new responsibilities on downstream users (DUs) of these chemicals i.e. those that purchase and use chemical products. In particular, for registered classified ...
